Water #2 Flashcards
What is a glacier?
A large body of ice formed from years of accumulation of snow that does not completely melt and, instead, accumulates and becomes compacted
What is a glacial advance?
When a glacier gets larger it is advancing. The terminal edge of a glacier is at the lowest end, or in the direction that the glacier is moving. If the terminal edge is further out than it was previously the glacier is advancing. In this situation, the glacier is accumulating ice faster than it is melting and the ice is slowly advancing downhill
What is a glacial retreat?
When a glacier gets smaller it is retreating. The terminal edge of a glacier is at the lowest end, or in the direction that the glacier is moving. If the terminal edge is behind the location it was previously, the glacier is retreating. In this situation, the glacier is melting faster than the ice is accumulating and the ice is slowly retreating backwards
What is the glacial movement?
The movement of glaciers from their source, changing landscape
What is the hydrosphere?
Combination of all the water on earth including lithosphere and atmosphere
What is the water cycle?
Condensation and evaporation (and precipitation)
What is the atmosphere?
Surrounding environment that rain “vanishes” into
What is the lithosphere?
Earth’s crust that the drainage seeps through
What is mass?
A coherent body of matter with no necessary shape
What is volume?
The amount of space that a substance or object occupies, or that is enclosed in a container
What is density?
The degree of compactness of a substance
How does the water cycle work?
Water storage in: the ocean, the atmosphere, ice and snow, the ground.
Cycle: evaporation, condensation, precipitation, runoff.
